| 设计密炼机非对称转子，对呈0°，90°，180°相位关系的两非对称转子和两同步四棱转子混炼过程进行模拟分析和应用研究。模拟分析表明，在混炼时间为5，10，15 s时，呈90°与180°相位关系的两非对称转子对天然橡胶（NR）颗粒和炭黑N330颗粒分散效果基本相同。应用研究表明：在相同密炼机填充因数下，呈0°，90°，180°相位关系的两非对称转子和两同步四棱转子对应的排胶温度差异不大；当密炼机填充因数为0.65时，呈180°相位关系的两非对称转子对应的胶料门尼粘度最小，t90最短，炭黑分散度、Fmax－FL、100%定伸应力、300%定伸应力、拉伸强度、撕裂强度最大，呈90°相位关系的两非对称转子对应的胶料拉断伸长率最大。 |

| The asymmetric rotor for the mixer was designed，and the simulation analysis and application research on the mixing processes of two asymmetric rotors and two synchronous four-wing rotors in 0°，90° and 180° phase relationships were carried.The simulation analysis showed that，when the mixing time were 5，10，15 s，the two asymmetric rotors in 90° and 180° phase relationships exhibited nearly identical dispersion effects on natural rubber （NR） particles and carbon black N330 particles.The application research showed that，when the filling coefficient of mixer was identical，the discharge temperatures corresponding to the two asymmetric rotors and the two synchronous four-wing rotors in 0°，90° and 180° phase relationships displayed negligible differences.When the filling coefficient of mixer was 0.65，the Mooney viscosity of the compound corresponding to the two asymmetric rotors in 180° phase relationship was the minimum，thet90 was shortest，the carbon black dispersion，Fmax－FL，Shore A hardness，modulus at 100 %，modulus at 300%，tensile strength and tear strength were the maximum，and the elongation at break of the compound corresponding to the two asymmetric rotors in 90° phase relationship was the maximum. |
